Flat hosiery frame



0- 1934- w. HEINITZ FLAT HOSIERY FRAME Filed Jan. 21, 19255 PatentedOct. 23, 1934 UNITED STATES PATENT OFFICE FLAT HOSIEBY FRAME ApplicationJanuary 21, 1933, Serial No. 652,865 In Germany April 16, 1930 3 Claims.(C1. 66-128) The invention relates to a device for limiting the throw ofthe thread guide bars in flat knitting machines and particularly refersto a device for limiting the throw of each bar independently of that ofthe others by means of pattern pins serving as stops.

To avoid the necessity of extending these pattern pins beyond thesections necessary for the patterning if, for instance, the same patternis to be produced at another part of the width of the fabric, the threadguide bar according to the invention is so constructed that extensionmembers of different length may be connected to its ends.

In this way it is possible to effect the patterning at any desired partof the width of the fabric without altering the arrangement of thepattern pins. Moreover, after removing the extension members the threadguides may be brought out of the operating position without the barsrequiring particularly much space at the sides of the machine.

By inserting extension members'the intermittent guidance of the threadcarried according to the pattern may be effected either in the middle orin the side parts of the fabric without changing the pattern pinarrangement. This selective guidance permits patterning on any walewithin the fabric width without requiring a rearrangement of the patternpins.

By way of example, one embodiment of the invention is illustrated in theaccompanying drawing, in which Figure 1 is a front view of the deviceand Fig. 2, a top view thereof.

Referring to the drawing, thebars 1 which preferably are of equal lengthand carry the thread guides 2 have a hook on both ends to receive thebooks of the extension pieces 3, 3' which may differ in length. Eachthread guide bar, therefore, consists of the bar 1 carrying the threadguide 2 and the extension members 3 and 3', each of which is providedwith an adjustable end stop 4 and 4', respectively. Within range of thestops 4 and 4', work pins 8 are carried by the pattern chains '1.

The division of the thread guide bars permits variations in the totallength thereof in the simplest and quickest way possible.

By the employment of extension members 3,

3' of corresponding length, the working range of co the thread guide maybe rapidly and easily transferred to any part of the fabric while thedifferent length of the pins 8 makes patterning possible within thisrange.

For example, by means of correspondingly chosen extension members 3, 3'the path of the thread guide 2 towards the left or right may be limitedto certain portions of the width of the fabric and by using pins 8 ofdifferent length a steady progressive or a jumping change of the throwmay be effected within this range in the individual wales, therebyincreasing the possibility of patterning and permitting the productionof any pattern by simple means.

I claim:-

1. Device for limiting the path'of thread guide bars in fiat hosierymachines, comprising thread bars having hooked ends, extension piecesprovided with hooks on one end for connection to the ends of said bars,said pieces differing in length, and adjustable stops carried on theother end of said pieces.

2. In a device for limiting the throw of the thread guides in flatknitting machines, in combination with thread guide bars each carrying athread guide, extension members of different lengths adapted to behooked to the ends of said guide bars, and adjustable stops carried bythe free end of said hooked extension members.

3. In a device for limiting the throw of the thread guides in flatknitting machines, in combination with thread guide bars each carrying athread guide and provided with a hook at both ends, and extensionmembers of different lengths each of which carries a hook at one end andan adjustable stop at the opposite end.
